Summary

This study investigated pediatric electrosurgical dispersive electrode safety, finding that higher currents and longer durations increase thermal effects. Electrode perimeter, not surface area, is key to minimizing temperature rise and burn risk.

Area of Science:

  • Biomedical Engineering
  • Medical Device Safety
  • Electrosurgery

Background:

  • Electrosurgical dispersive electrodes are crucial for patient safety during surgery.
  • Concerns exist regarding the thermal performance and potential burn risks associated with these devices.
  • Pediatric electrodes require specific safety considerations due to unique physiological factors.

Purpose of the Study:

  • To investigate critical factors influencing the thermal performance of pediatric electrosurgical dispersive electrodes.
  • To evaluate the impact of current intensity, duration, medium resistivity, contact area, and gel water content on electrode temperature.
  • To determine the relationship between electrode geometry and thermal effects.

Main Methods:

  • A model system simulating human thermal effects was developed.

  • Varied parameters including current (1-3A), duration (60s), medium resistivity, contact area, and adhesive gel water content.
  • Measured maximum temperature rises (delta Tm) under the electrodes.

    • Main Results:

    • Temperature rise (delta Tm) increased with current intensity, duration, and medium resistivity.
    • Reduced contact area or water content in the adhesive gel led to increased delta Tm.
    • Maximum temperature increase was inversely proportional to the square of the electrode's perimeter.

    Conclusions:

    • Electrode perimeter, not surface area, is the critical factor for thermal performance.
    • Currents and durations exceeding routine electrosurgery use were employed, highlighting potential risks.
    • Monitoring interface impedance can mitigate burn risks associated with electrosurgical dispersive electrodes.
